WINDOW-WASHING DEVICE.

Specication of Letters Patent.

Application filed October 27, 1916. Serial No. 128,127.

To all 'whom t may concern:

Be it known that we, GIUSEPPE BERTO- LINI and ToMAsso CAPPELLETH,subjects of the King of Italy, and residents of the city of Chicago,county of Cook, and State of Illinois, have invented certain new anduseful Improvements in Window-Washing Devices, of which the following isa specification.

Our invention relates to improvements in window washing devices and hasfor its object the production of a device of this character through themedium of which the outer side of a window may be readily and easilywashed without the necessity of the operator or washer passing throughthe window to the outer side thereof, theconstruction being such as topermit of the washing of the outer side of a window by an operatorpositioned at the inner side of the window. A further object is theproduction of a device, as mentioned, which will be of durable andeconomical construction and elcient in use. Other objects will appearhereinafter.

The invention consists in the combinations and arrangements of partshereinafter described and claimed.

The invention will be best understood by reference to the accompanyingdrawings forming a part of this specification, and in which,

Figure 1 is a vertical section through a window in conjunction withwhich is arranged a window washing mechanism, embodying the invention,

Fig. 2 is an elevation of the construction shown in Fig. 1, viewed fromthe outer side of the window,

Fig. 3 is an elevation viewing the window and washing mechanism from theinner side of the window,

Fig. 4 is a section taken on substantially line m-m of Fig. 1, and

Fig. 5 is a detail section illustratin the method of actuation of thelazy tong evice included in the construction.

The preferred form of construction as illustrated in the drawings isdesigned for usein connection with a conventional window sash 1 which isslidably mounted in a window frame 2. The mechanism comprises a guiderail 3 inthe form of a T iron which is adapted to rest upon the outersill of the window adjacent the lower edge of the window sash, thelatter being raised slightly to permit of insertion or application ofthe mechanism. The rail 3 is held in proper position by means of hooks 4carried thereby which are adapted for engagement with eyes or loops 5provided upon the inner sill of the window.

Mounted for travel upon the rail 3 is a carriage 6 at the upper side ofwhich are provided two spaced wheels 7 adapted for engagement with theupper side of said rail 3. To insure travel of the wheels 7 along therail, said wheels are provided at. their peripheries with spaced radialpins which are adapted for engagementwith spaced perforations 8 formedin the rail, as seen. Also provided in the carriage at the under sidethereof are four wheels 9 which are adapted to engage with the underside of the upper fiange of the rail to hold the carriage secu'rlely inthe travel of the same along the ral The wheels 7 are loosely mountedupon a shaft 10 which is rockingly mounted mthe carriage 6, the innerend of said shaft being adapted to project through the opening below thewindow sash, as clearly shown in operating with the outer end portion ofthe shaft 10 is a lazy tong device comprising an elongated guide armllin the form of a T iron which 1s secured rigidly to said shaft.

Patented Mar.. 19, 1918-.

Coperating with guide arm 11 is a lazy I tong member 12 having angularlyformed enga ing lingers 13 which are adapted to slida ly engage withsaid arm, as clearly shown in the several views. gers 14 of the lazytong member are held fast to the arm 11 by means of pins 15, as clearlyshown in Fig. 2. The arrangement is such that. said lazy tong member maybe extended and contracted by sim ly oscillating the lower divergingends o the lowermost links of said lazy tong member. A helical tensionspring 16 interposed between and connecting said lower ends of saidlowermost links serves normally, to hold the lazy tong member inextended condition. Contraction of said lazy tong member is effected bymeans of two spaced gears 17 The lower finioo which are rotatablymounted upon the inner side of arm 11 adjacent the lower end thereof.Links 18 serve to connect the gears 17 withA the lower ends of saidlower links, as clearly shown in Fig. 5. The gears 17 mesh with an idlergear 19 which, in turn, meshes with a gear 20 which is xed to a shaft 21rotatably mounted in bearings provided in the lower end portion of arm11. The arrangement is such that, through rotation of shaft 21, thedivergently disposed lower ends of the lower links of the lazy tongmembermay be rocked upwardly in order to contract saidI lazy tongmember.

With this arrangement then it will be seen that expansion andcontraction of the lazy tong member may be effected with ease andrapidity by simply rotating the shaft 21,

since, when this is done, the links 18 willeffect contraction of saidmember and the spring 16 expansion of the same. A hand wheel 21 isprovided at the inner end of' shaft 21 for manual engagement.

Carried at the upper end of the lazy tong member 12 is a brush 22 whichis adapted, upon actuation of said lazy tong device, to engage with theouter side of the window pane, as clearly shown in Fig. 1. The back ofsaid brush is formed with a semi-circular slot 22 with which slidablyengage headed pins 22 which are provided at the upper ends of theuppermost links of the lazy ton member. 4

C eansing liquid is supplied to the brush 22 through the medium of a pum23 which is mounted upon the lower en of guide arm '11, said pump beingoperated upon rotation or oscillation of the shaft 21. A supply pipe orhose 24 communicates with the lower end of said pump, said pipe or hosebeing connected with any suitable source of supply, a pipe or hose 25extending from the upper end of said pump to thel brush 22, as seen. v

Pivotally connected at 26 with the inner end of shaft 10 is an angularhandle 27 which is normally held in elevated position by means of ahelical tension spring 28, a pawl or dog 29 pivotally connected withsaid handle and which is adapted to engage at its outer end with arecess 30 provided 1n said shaft, serving to lock said handle inoperative position.

With the construction set forth it will be seen that in the washing of awindow, the sash is first slightly elevated and the rail 3 arranged uponthe window sill, being locked in position by hooks 4. Similar hooks 3lare preferably provided for engagement with eyes 32` provided upon ythesash for locking the latter in the desired elevated position. The devicehaving been arranged, as shown, and the water supplied through the pipe24 to the pump 23, 1t is only necessary to actuate the handles 21 and 27in order to effect actuation of the lazy tong member, both in the way ofextending and contracting the same, oscillating said member laterallyand moving the same bodily along the rail in order to effect moving ofthe brush 22 to engagement with all parts of the window in the cleansingoperation. The brush is automatically supplied with water during theactuation of the same, so that a thorough cleansing of the window isei'ected.

While we have illustrated and described the preferred form ofconstruction for carrying our invention into effect, thiseis capable ofvariation and modification without departing from the spirit of theinvention. We, therefore, do not wish to be 'limited to the precisedetails of construction set forth, but desire to avail ourselves of suchvariations and modifications as come within the scope of the appendedclaims.
